Job description

Company Overview

Sigma Connectivity is a tech house with a big heart for technology, people, and turning clever ideas into real products. We are a team of around 700 engineers, with our main office in Lund, Southern Sweden, and colleagues across Sweden, the US, UK, Poland, Germany and Denmark.

We work with connected products, cloud solutions, consumer electronics, IoT devices and everything in between. Sometimes that means helping a customer shape an early idea. Sometimes it means building, scaling, testing and shipping the solution. Quite often, it means solving tricky problems together over coffee.

Our culture is built around curiosity, collaboration and a healthy dose of Nordic work‑life balance. We like people who share knowledge, ask questions, try things out and enjoy building great technology together. At Sigma Connectivity, you will never work alone – unless you really need five minutes to debug something mysterious.

Job Overview

We are looking for a Senior Cloud Fullstack Developer who enjoys working across the full stack, from cloud services and backend development to frontend experiences and DevOps practices.

In this role, you will be part of a skilled and friendly team where Java, TypeScript and IaC are central parts of our daily work.

You will help design, build and maintain modern cloud‑based solutions, contribute hands‑on in projects, and work closely with colleagues from different technical disciplines.

You might spend one day developing backend services, another day improving a React frontend, and the next helping the team make deployments smoother, safer and more automated.

We like people who enjoy variety, take ownership and are happy to share both good ideas and bad puns.

This is a role for someone who wants to build robust software, learn new things, influence technical direction and have fun with a team that genuinely enjoys working together.

The Role

This is a senior, hands‑on role for someone who enjoys building cloud solutions end to end and making teams more effective along the way. You will work across backend, frontend, infrastructure and delivery practices, with a mix of product thinking, engineering quality and practical problem‑solving.

You will contribute to:

• Designing, developing and maintaining cloud‑based applications and services
• Building APIs, backend services and user‑facing features
• Working with Java, TypeScript and IaC in modern software solutions
• Improving CI/CD pipelines, infrastructure automation and deployment workflows
• Helping the team build systems that are scalable, secure, observable and maintainable
• Translating customer needs into practical technical solutions
• Sharing knowledge through code reviews, technical discussions and collaboration

Bringing positive energy to the team – technical sharpness is great, but being fun to work with matters too.

Requirements

To succeed in this role, we believe you have:

• Several years of experience (7+) in software development, preferably in cloud-based or distributed systems
• Strong hands‑on experience with Java, TypeScript and similar languages
• Experience working across both backend and frontend development
• Practical experience with cloud platforms and cloud‑native development
• Experience with IaC, CI/CD and modern DevOps practices
• Good understanding of software architecture, design patterns, scalability, clean code and technical quality
• Ability to make pragmatic technical decisions and explain trade-offs clearly
• Good communication skills in English
• A collaborative mindset and a willingness to help others grow

Preferred qualifications

It would be a bonus if you also have experience with:

• Spring, Spring Boot – React, Vue.js
• AWS, Azure or Google Cloud
• Docker and container‑based development
• Kubernetes or similar orchestration platforms
• Terraform, CloudFormation or similar infrastructure tooling
• Microservices, event‑driven architecture or API design
• Monitoring, logging and observability
• Automated testing and quality practices

Most importantly, you are curious, open‑minded and enjoy solving problems together with others. You care about quality, but you also know that great software is built by people – and that work is better when the team enjoys the journey together.
